This panel looks at your thyroid health. Thyroid hormones control the body's metabolism, which is why imbalances in thyroid hormones can affect virtually every metabolic process. This panel includes basic tests such as TSH, free T4, and free T3, as well as total T4, and total T3.
Preparation: Please do not exercise prior to testing. It is best that your blood is taken in a rested state.
Fasting for 8-12 hours is also required. You should also discontinue biotin supplements a few days before your lab work.
